SPECIFICATION forming part of Letters Patent N o. 642,898, datedFebruary 6, 1900.

Application tiled I une 3, 1899. Serial No. 719,270. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM H. DENMAN, a citizen of the United States,residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented certain new and useful Improvements inHorseshoes, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, of which-Figure lisa plan view; Fig. 2, a section on line 2 2, Fig. l; Fig. 3, asection on line 3 3, Fig. 1; Fig. 4, a plan view of a modiiication ofthe pad portion of the shoe; Fig. 5, a section on line 5 5, Fig. 4.

This invention relates to elastic-tread horseshoes; and its object is toprovide a means for securing in a simple and eiiicient manner the padsor calks to the shoe.

The invention consists in the combination, with an ordinary metalhorseshoe formed of an integral piece of metal, of a pad or pads ofindia-rubber or other suitable elastic or yielding material, that aresecured to the shoe by means of a rivet having an enlarged head, that iscontained ina corresponding socket or cavity in the body of the pad, andwhose shank extends through a hole in the shoe and is secured to thelatter, as hereinafter described, whereby, while the said pad or padsmay be readily aflixed and removed,when the shoe is devoid of the saineit may be used as an ordinary metal shoe Without its utility for thatpurpose being affected.

In carrying out my invention, reference being had to the accompanyingdrawings, forming a part of this application, I make, by casting orforging, an integral horseshoe 1 of suitablemetal, which does not or maynot differv in form from an ordinary horseshoe, except that it isprovided with through-holes 2, usually onlyin the toe and heel portions,respectively.

3 are toe and heel pads or calks of elastic india-rubber, in which isformed a socket or cavity 4, adapted to receive the head 5qd of ametallic rivet 5, whose shank 5b is of considerably less diameter thanthe head 5a and eX- tends through the said hole 2 in the shoe, and itsprojecting end is turned over and riveted on the latter, as clearly seenin thedrawings.

I prefer to make the head of the rivet tapering, as shown, and I alsoprefer to provide on the end of the head a circular flange 5, so as tobetter insure the retention of the pad by the rivet.

. The purpose of having the head tapering, as shown, is to prevent therivet from being forced against the animals hoof when the shoe is inuse. Other means for effecting a similar result may be employed-as, forinstance, by making the part adjacent to the iiange 5, encircled by theindia-rubber, cylindrical or' straight-sided and of larger diameter thanthe shank, wherebysthe end next to the latter will abut against theshoe.

It will be obvious that by the described construction the pad will besecurely maintained in place, and when it is worn out it may be readilyremoved by removing the shoe from the foot of the animal and thenforcing out the rivet and a new pad may be substituted.

I remark that I usually embed the head of the .rivet in the body of thematerial composing the pad in the process of making or molding thelatter. I also remark that it will be obvious that in case it shall notbe desired to use the pads the shoe, with the holes therein, may be usedas an ordinary horseshoe.

I sometimes extend the pads 3 to cover the 'whole face of the shoe-thatis, the under side when the latter is on the animal-except along theline of the usual nail-holes 6, as seen in Figs. 4 and 5.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination with the horseshoe, of the elastic oryielding pad, the rivet having the enlarged head Within a correspondingcavity or socket of the pad, and its shank extending through a suitablehole in the shoe and hav' ing its projecting end turned over andriveted, and means limiting the protrusion of the rivet toward theanimals hoof when the device is in use, substantially as and for thepurpose described.

In testimony whereof I have' hereunto vaffixed my signature this 11thday of April, A. D. 1899.

WILLIAM H. DENMAN.
